The follow-up of anthropometric percentiles such as triceps and mid-thigh skinfold thickness (TSF, MTSF), mid-upper arm and mid-thigh circumferences (MUAC, MTC), and arm and mid-thigh muscle areas (AMA, MTMA) after a resistance training might allow for detecting nutritional progress of fat and muscular tissue during the treatment of anorexia nervosa restricting (AN-R) type patients.
A total of 44 AN-R patients were randomized for control (CG 13.0 ± 0.6 years) and intervention (IG 12.7 ± 0.7 years) groups after hospitalization. The intervention group underwent a resistance training program of 8 weeks following the guidelines for healthy adolescents (3 days/week; 70 % of 6 RM). All measurements were obtained prior to starting the program (PRE) and after 8 weeks of training (POST) in both groups. TSF, MTSF, MUAC, and MTC were measured, and AMA and MTMA were calculated. Data were matched with percentile tables for general population. Changes were assessed using statistical tests for categorical data.
The distribution of percentile categories within the groups did not differ statistically after 8 weeks (p > 0.05). After training, 73 % of the patients were at the same percentile interval of MUAC, 18 % higher and 9 % lower, while 30 % of CG was at lower percentile categories. Further, 54 % of the IG patients remained at the same percentile interval of MTC after training, and 36 % higher, while 20 % were at lower categories in the CG. The AMA increased (32 %) after training or remained at the same interval (59 %) in the IG, while the IG showed greater frequency of percentile decreases (45 %).
Anthropometric measurements could be useful for assessing muscle status in AN-R patients during the treatment process. However, exact standard deviation scores should be used instead of percentile categories to increase the sensitivity to changes in TSF, MTSF, MUAC, MTC or AMA.
对三头肌和大腿中部皮褶厚度（TSF、MTSF）、上臂中部和大腿中部周长（MUAC、MTC）以及上臂和大腿中部肌肉面积（AMA、MTMA）等人体测量百分位数进行随访，可能有助于在神经性厌食症限制型（AN-R）患者的治疗过程中检测脂肪和肌肉组织的营养状况进展。
44例AN-R患者住院后被随机分为对照组（CG，13.0±0.6岁）和干预组（IG，12.7±0.7岁）。干预组按照健康青少年指南进行了为期8周的抗阻训练计划（每周3天；6RM的70%）。两组均在开始训练前（PRE）和训练8周后（POST）进行所有测量。测量了TSF、MTSF、MUAC和MTC，并计算了AMA和MTMA。数据与一般人群的百分位数表进行匹配。使用分类数据统计检验评估变化。
8周后，两组内百分位数类别的分布在统计学上没有差异（p>0.05）。训练后，73%的患者MUAC处于相同的百分位数区间，18%更高，9%更低，而对照组30%处于较低的百分位数类别。此外，训练后IG组54%的患者MTC保持在相同的百分位数区间，36%更高，而对照组20%处于较低类别。IG组训练后AMA增加（32%）或保持在相同区间（59%），而IG组百分位数下降的频率更高（45%）。
人体测量对于评估AN-R患者治疗过程中的肌肉状况可能有用。然而，应使用确切的标准差分数而非百分位数类别，以提高对TSF、MTSF、MUAC、MTC或AMA变化的敏感性。
